Front Seats Manual Seats This section tells you about the seats - how to adjust them, and fold them up and down. {CAUTION: You can lose control of the vehicle if you try to adjust a manual driver's seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you don't want to. Adjust the driver's seat only when the vehicle is not moving. Move the lever located under the front of a manual seat up to unlock it. Slide the seat to where you want it and release the lever. Try to move the seat with your body to make sure the seat is locked into place. 1-3
